no signal on displayport output
only 2 screen detected in display setting on windows 10
need a minidp > dvi-d adaptater ?
Good day papourien,
That card was far ahead of its time š
This card supports more screens than 2 however you will have use the Eyfinity feature of the card. You do this by using the DP ouput of the card. When connecting a Screen with DP in put you can use a passive adapter, when using a screen without DP input you will need to use an active adapter with Eyefinity support.
Which HD7770 card do you have (brand/Type)? So i see the outputs on the card …
If i understand correctly your screens areĀ
Screen 1 is VGA inputĀ
Screen 2 and 3 have DVI input.
All screens are 1920 x 1080 ?
hi mst,
the graphic cart is a msi R7770 2PMD1GD5/oc
dvi-i + hmid + 2 mini display
and the screens are one 1920×1080 and two 1024×1280
it’s a cheap configuration but realy usefull, i used it with on a intel hd505 chipset
i dont really need eyefinity, i prefer 3 independant ecran for multitask
after all i read, my config would works with a active adaptaeur, but the both i’ve tried din’t works
i’m thinking about buying a miniDP/DP cable for testing my dp output on friend’s native DP screen
maybee a good active adaptater fix my problem…
if not, i’ll change one screen…
i’ll go forĀ CAC-2170, will see…
Hi papourien,
If your screens have HDMi input a CAC-2170 will do fine,
If it is only DVI than a CAC-1152 will be good.
my screen are dvi, but i’ve the cable hdmi/dvi in 10ft, if i can keep it
will be a problem ?
that would be depend on the cable but could be an issue yes.
certainly if your cable is an active one it will most probably not work
same result, dont works :'(
no screen detected, at least, the screen detect the cable and go sleep
the cable is a standard hdmi/dvi bidirecrtionnal
i’ll try the dvi one and if works, buy a 3m dvi/dvi cable…
thanks amazon’s politicy return
thanks for the feedback and sorry for the inconvenience
no work with minidv>dvi activ adapt š
i dont understand…
i need a true displayport screen for trying my video output…
Try connecting the Mini DP – to DVI active adapter plus only 1 extra external screen to see if that works …
no wokrs
i tried boot pc with one screen on display port without success
sounds like the DP output is not working at all ….
so…my graphic card works with Benq screen with midi DP > DP cable
after 4 different “active miniDP > something” adaptator, i’ll go for a screen…
thanks for the feedback
